Abstract
This paper provides a brief review of the history and development of mini screws and presents its structural features, with particular reference to the screw sizes relevant to clinical orthodontics, site selection and the different placement techniques. It covers the clinical applications of miniscrews, incorporating the principle of direct and indirect anchorage as well as the use of intraoral auxiliaries for distal movement of molars. The role of palatal miniscrews for retraction of anterior teeth, and when used in combination with buccal miniscrews for intrusion of buccal teeth is also covered along with the possible causes of miniscrew failure. Finally, a conclusion is put forward that the use of miniscrews in orthodontics has a valid clinical basis and will enhance the scope of orthodontic practice.
